Total DVD and Blu-ray disc sales in 2009 were $8.72 billion. For the purposes of this problem, you will combine DVD and Blue-ray disk sales into one category of DVD sales. A study by In-Stat predicted that "physical disc sales will decline by $4.7 billion by 2014," and that "streaming, on the other hand, should grow from its current $2.2 billion to $6.3 billion over the same time period (2009–2014). d. Write an equation that represents the linear model for streaming videos. Let S = the total sales of streaming videos in billions of dollars, and t = the number of years after 2009. e. In what year do the models predict streaming video sales to exceed DVD sales?

Explain what is meant when two variables are positively linesrly related. What would scatter plott look like? Two variables x and y are postively linearly related if when the x value increases , the y value increases or decrease? The points on a scatter plot fall approximately in a-an ascending straight line b- a descending curve c- a descending straight line or d- an ascending curve from left to right?
New York City received a federal grant of $ 100 million for improving public transportation. The funds are to be used only for purchases of new buses, purchases of new subway cars or repaving of city streets. Costs are estimated at $ 150,000 per bus, $180,000 per subway car, and $ 250,000 per mile repaving. City officials want to determine different ways of spending the grant money. Determine the linear equation. Further, if it has been determined that 100 buses and 200 new subway cars will be purchased, how many mils of city streets can be repaved? A portfolio manager is concerned that two stocks generate an annual income of $15,000 for a client. The two stocks earn annual dividends of $2.40 and $ 3.50 per share, respectively. If X equal the number of shares of stock 1 and y equals the number of shares of stock 2. Rewrite the equation in slope-intercept form and interpret the meaning of the slope and y intercept. Solve for the x intercept and interpret its meaning?
